Attenuating element consisting of a head part, neck part and base part. The neck part is narrower compared to the head part and neck parts of adjacent attenuating elements form a continuous channel. Via the head parts, this channel is connected so that the cross-sectional area of the head parts is smaller than the cross-sectional area of the base parts. In this way, a water-control structure, sound-attenuating wall and the like can be provided. Such attenuating elements can be produced in a very simple manner by dividing them vertically and producing each of the vertical parts from concrete in a mould.
